To all whom it may concern:

Be it known that 1, JAMES C. GLEED, a citizen of the United States, residing at North Yakima, in the county of Yaln'ma and State of Washington, have invented certain new andxuseful Improvements in R0- tary Pumps, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in rotary pumps and has relation more particularly to a device of this general character wherein radially movable blades are carried by a rotor and wherein said blades coact with a hub eccentrically positioned relative to the rotor for imparting requisite movement to the blades; and it is an object of the invention to provide a novel and improved device of this general character wherein the hub is readily removable and can be replaced when required by the necessities of practice.

It is also an object of the invention to provide a novel and improved device of this general character wherein the stator includes a removable side plate and wherein said removable side plate coacts with the rotor to allord a support therefor.

A still further object of the invention is to provide a rotary pump of this general character having novel and improved means wherein the parts. subject to wear may be' readily replaced whereby the life of the pump may be materially prolonged.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved pump whereby certain important advantages are attained and the device is rendered simpler, less expensive and other- Wise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed. I

In order that my invention may be the better understood, I W111 now proceed 'to describe the same with reference to the accompanying drawings, wherein- Figure 1 is a vertical sectional view taken through a pump constructed in accordance with an embodiment of my invention and at right angles to the axis of the rotor;

Fig. 2 is a transverse vertical sectional view taken through my improved pump as herein embodied;

proved and with the shaft of the rotor shown in Fig. 3 is a side elevational view of my im pump with 'a side plate removed section;

Fig. 4 is a view in elevation of the inner face of the removable side plate as herein disclosed;

Fig. 5 is a View in end elevation of the removable hub as herein embodied; and

Fig. 6 is a longitudinal vertical sectional view taken through Fig. 5.

As herein embodied, S denotes the stator of my improved pump and which includes a casing 1 affording a substantially'circular chamber having in communication therewith. at the upper portion of the casing the induction and eduction ports 2.

A side face of the casing 1 is open and said open side face is adapted to be closed by the removable side plate or head P. Depending from the casing l' are the supporting legs 3 of any ordinary or preferred type and for a purpose which is believed to be clearly apparent to those skilled in the art to which my invention appertains.

Disposed transversely through the casing I'abovebut in vertical alinement with the axial center of the chamber within the easing, is the shaft 4 also adapted to bedisposed through the removable plate or head P when my improved pump is assembled, and said shaft 4 extends beyond opposite sides of the casing 1 and is adapted to be driven from any suitable sourceof power coupled with either of the extended portions of the shaft.

The fixed side plate or head 5 of the casing 1 is provided .with 'a depressed portion 6, the peripheral wall of which being concentric to the shaft 4 and the removable plate or head P is proyided in its inner face with the depressed portion 7 of the same diameter as the depressed portion 6 and also concentric to the shaft 4 when said plate or head P is in applied position.

Arranged within the casing 1 is a hollow rotor R having a side portion seated within the tapered portion 6 of the stator S and which is provided with the hub 8 keyed or adapted to be closed by the removable head or plate P, arid the central portion of the plate or head P is provided with an enlarged opening 10 into which extends the "in disclosed as roller bearings suitably mounted within the retaining rings It I will'be at once self-evidentthat the flanges shanks 18 of the ing unduly worn I 1 Disposed through 11 and 12 together with the interposed antifriction members 14 afford an additional support for the rotor R and wherebythe same may be permitted to rotate withja minimum of frictional resistance. It is also to be noted as particularly illustrated in Fig. 2, that in order that the fflanges 11 and 12 may have increased bearing surfaces the plate 1? is further depressed, as indicated at 16. 1

The periphery of the rotor R is provided with the transverse openings orslots 17 herein disclosed as four in number and equidistantly spaced, and slidable through each of said slots 17 is a blade B. Each pair of opposed blades B is provided at one side portion thereof with an inwardly directed shank or extension 18 which is adapted to be received between the spaced ears 19 carried by the central portion of the sides of an elongated yoke 20. The extensions or blades are detachably held to the ears 19 through the medium of the removable members 21 whereby it will be at once self-evident that the blades B may be readilyremoved and replaced when the requirements of practice may so necessitate.

the yokes 20 is the stationary cam member 22 with which the intermediate portions of the yokes 20 are adapted to contact, and as is clearly illustrated in Figs. 1, 2 and 3, it is to be noted that the portions of the yoke coacting with the cam 22 are provided with the lining blades 23 which directly contact with the periphery of the cam 22. These plates 23 are adapted to be removed as clearly disclosed in Fig. 2 so that upon a plate becomthe same may be readily and conveniently replaced so that the life of the pump ismaterially prolonged.

' The cam 22 as hereinbefore referred to is tubular and the shaft 4 extends therethrough tion of the opening and as is clearly illustrated in the accom panying drawings, the cam member 22 is cylindrical in form and arranged eccentrically to the shaft 4:. One end of the cam 22 is closed, as indicated at 241, with the excep- 25 through which the shaft 4 is disclosed. The closed end of the cam 22 is provided with an arcuate shoulder inbefore referred to.

26 which is continued by the. arcuate flange 27 whereby an annular shoulder is afforded and which is annular recess 28 formed in the inner Wall of the free endportion of the flange llhere- The closed end 2 1 and the flange 27 of the cam member'22 are provided with the openings 29 and through which are disposed the headed members 30 which are in threaded engagement with the removable plate or head 'P whereby it will be at once self-evident that upon removal of the plate or head P the cam member 22 will also be withdrawn. By this arrangement the cam 22 may be readily replaced-when the requirements of practice may necessiadapted to be seated within the i tate and without the necessity of disassembli'ng the entire pump.

a It has also been'found of particular advantage to secure to the under surface of the peripheral wall of the rotor R at opposite sides ofeach of the slots 17 the steel plates 31 continued or otherwise held in applied position but which are adapted to be readily removed and replaced. I These plates 31 serve to take up wear whereby it will be at once perceived that the life of the pump is further prolonged.

It is preferred that the blades B be made of tempered steel but by the use of the wear plates 31 it will be at once self-evident that particular care need not be exercised in the character of metal from which the rotor R chilled cast iron and which is permissible in view of the fact that the same can be readily replaced when the requirements of practice so necessitate.

From the foregoing -description,'. it is thought to be obvious that a pump constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility withwhich it may be assembled, and it will also be obvious that my invention is susceptible of some change and. modification without material departure from the principles and spirit thereof and for thisreason I do not .wish to be understood as limiting myself to theprecise arrangement and formation of the several parts herein shown incarrying out my invention in practice, except as hereinafter claimed.
